Pairing / Programming Headphones

I have 3 kids, and only 2 pairs of headphones for the Rear Seat Entertainment system in my 2013 x166 GL 550. I bought a 3rd pair of headphones on eBay (Part No: A222 820 1889) identical to the existing OEM pairs, but can't find instructions on how to pair / program the new headphones to my infotainment system.

I took the car to the dealer and they said that they couldn't figure out how to pair / program the new headphones to infotainment system (gosh, really?). Now I am trying to figure out how to do it myself.

I found this article which explains that in some NTG infotainment systems there's a "dealer" menu in which a new set of headphones can be paired / programmed. I don't seem to have the same version of the NTG system (mine is v4.7) and have thus far been unable to locate a "dealer" menu (though I know of the engineering menu, which does't seem to have the same options).

I also found a YouTube video (screenshot below) that implies that the pairing / programming can be done through the Xentry software (I don't have access to this, and with a $37k price tag I won't be buying it anytime soon). Anyone know if there's an easier way to pair / program the headphones?

Did you ever figure this out?

My question is I have some used headphones that don't hat the UID listed. Not sure how to find that address or if the dealer knows how.
